aud a few scattered erect hairs extend forward from tins in 

 a line parallel with the outer mar«iin. The pygidinni is 

 moderately closely covered with close-lying elongate set.ie 

 of the same colour.

Tenasserim Mts., Siam Border {K. G. Gairdner). 



Two male s})ecimeus are all that I have seen of this. 

 It is a rather large species, and its chestnut-red elytra 

 are in well-marked contrast to the black pronotum, of 

 which the front and side margins are also reddish. The 

 scales with which the upper surface is decorated are of two 

 shades of yellow, pale upon the inner part and deep orange 

 upon the outer. The pronotum is almost circular in its out- 

 line and relatively longer than in the four species just 

 di scribed, and the elytra are not long in proportion, their 

 sides being distinctly dilated near the middle. Dejeania 

 hrenskei, Noufr., so far as can be judged from the description, 

 resembles T). rvfipennis, but the twice-stated dimensions 

 indicate an insect much larger tiian any species of the genus 

 at present known to me. Nonfried's statement that the 

 claws of D. brenskei are entire is most probably incorrect.
